Hey guys, I've been searching all day for an answer which I was unable to find thus leading me here, I got a notice in the mail today, I had no clue of what it could be, I opened the letter to find a check along with a notice (CP21E) it says *As a result of your recent audit, we changed your 2020 form 1040, as a result, you are due a refund of *REFUND AMOUNT*. * *Changes to your 2020 form 1040* Refund Due: *REFUND AMOUNT*, and under summary it has "Increase in credit". I was on unemployment in 2020 which I filed a return and got my refund for 2020, I assume this has to do with the *Lookback* option? I was employed in 2019 and I received CTC for that year, so I'm I correct in assuming that?
